Last year, the U.S. energy storage market nearly doubled, and it is expected to double again in 2019. In fact, the final quarter of 2018 broke the previous record for megawatt-hours deployed in a single quarter by 50%, according to a report from Wood Mackenzie Power & Renewables and the Energy Storage Association (ESA). Although solar-power projects are typically more likely to take advantage of battery storage, wind energy also benefits from storage in certain cases. For example, Texas’ largest energy storage site is co-located with a solar power plant — but it can make use of solar and grid-generated wind energy.
